ROLLING MILL.

. Application filed march 80, 1922. Serial Ho. 5%,.

To all whom it may concern:

Be it known that I, JOSEPH E. FAWEIJL. residing at Pittsburgh, in the county of Alleghen or discovered certain new and useful limprovements in Rolling Mills, of which 1mprovements the following is a specification.

I In the operation of three high mills as 'now constructed, it is neoesary to employ i: -lifting mechanisms, butalso on account of making provision for operatlng the feed rollers in the difierent positions of the tables. Furthermore, the employment of manipulators in connection with such vertically movable tables adds greatly to the ex ense of installation and maintenance.

- he invention described herein has -for one of its objects a construction of a three high mill, permitting of the feeding of the article being rolled 1n the same horizontal I plane for both the back and forth passes,

such end being attained by mounting the rolls in a vertically movable housing and the operation of the manipulating mechanism by and in accordance with the movement of the housing.

The inventlon has for it further object the provision of an improved manlpulator for such rolls. The invention is hereinafter .more fully described and claimed.

In the accompanying drawings forming "a part of this specification, Fig. 1 is a side elevation of a three high mill embodying the improvements claimed herein; Fi 2 .is a sectional plan view of the same; igs. "3,and 4 are a sectional elevation on a indicated by the line III-TH, Fig. 2 1llus-.

lane

trating alternate positions of the parts shown.

In the practiceof the inventlon, the housing 1, which is provided with windows, as

is customary, in which are mounted the bearings for the support of the different .rolls, is movably mounted in the frame and State of Pennsylvania, a- .citizen 0 the United States, have 1nvented vided with ribs 4 adaptable to enga e grooves in the vertical members of t e housing 1. In order that scale, etc., shall not interfere with the vertical movement of the housing, an opening is made through the base to permit the scale to drop into a pit 6 arranged in the foundation of the mill. Any su1table means may be employed whereby a vertical movement of the housing may be efiected. In

the construction shown, the shifting mechanism consists of a motor, for example, a fluid pressure cylinder 7 preferably hy draulic, and provided with a ram 8 to which is secured'a head 9 provided with trunnions 10 for the reception of the eyes at one end of the pitmen l1 which'have their opposite ends connected to an arm 12 on a shaft 13 mounted in suitable bearings carried by the base 2. This shaft 13 is provided with arms 14, and the ends of these arms 14: are pivotally connected to struts 15 having their upper ends arranged in bearings 16 on the underside of the housing 1.

As the housing and the rolls mounted therein will always be sufliciently heavy to insure their downward movement when mitted by the escape of fluid from the cy inder 7, the latter is made of a single acting character and is em loyed merely for raising the housing. uitable means are employed to prevent the too rapid downward movement of the housing, such for example as that shown, consisting of the cylinder 17.

In the construction shown, the controlling cylinder 17 either has its outer end opened or is provided with an escape port ting the free outward flow of air w en the piston moves to the left, and with a port controlled by a valve of any suitable construction, and indicated at 19, which will control the escape of air as the piston is drawn to the right by the downward movement of the housing. This controlling mechanism may be so constructed in proportion relative to the downward movement of the housing that when the housing is in the desired down position, I the piston will bear against the right hand end of the cylinder and hold the housing from further movement. It is preferred, however, to limit the downward movement of the housing by means of lugs 1 formed on the sides of the housing and adapted to bear onthe vertical guide posts 3 of the frame when the housing is in its lowered position. It

er- I ermitn maeea multaneously turnin the blanks and means coordinate with the ousing shitting means for operating the manipulator.

3. In a rolling mill the combination of a frame having vertical guide members, a housing movably arranged in said frame, upper, lower, and intermediate rolls carried by said housing, a shaft provided with arms extending under the housing for moving it 10 vertically, stationary feed tables arranged on opposite sides of said frame, a manipulator arranged with one of said tables for moving blanks across the rolls and for simultaneously turning the blanks, and a motor connected to said shaft and to said manipulator for simultaneously turning the shaft and operating the manipulator.

In testimony whereof, I have hereunto set m hand.

y JOSEPH E. FAWELL.
